Description

Technical Field

[0001] The utility model relates to the technical field of spinning cylinders of coated yarn machines, in particular to a spinning cylinder of coated yarn machines which is easy to adjust. Background Art

[0002] The covered yarn machine is a spinning equipment, which is mainly used to cover chemical fiber filament or yarn on the core wire to form a composite structure of silk thread, also known as covered yarn or wrapped yarn. This kind of silk thread has excellent wear resistance, wrinkle resistance and elasticity, so it is widely used in the textile industry. The main function of the spinning drum is to wind up the yarn for subsequent textile processing and use. During the spinning process, the yarn will be wound around the spinning drum, and the yarn will be gradually wound up by rotating the spinning drum to form a yarn roll of a certain shape.

[0003] According to the Chinese patent CN201720096280.X, in this application, the positioning column is placed in the positioning groove after passing through the main installation groove and the transition groove in sequence, and the positioning column and the positioning groove are tightly matched, which solves the problem of convenient disassembly and assembly of the cylinder and the support plate;

[0004] Although the locking assembly in the application can effectively solve the problem of convenient disassembly and assembly of the cylinder and the support plate, during use, the vibration of the spinning cylinder may cause uneven winding of the yarn, resulting in an uneven surface of the yarn. This uneven winding will also affect the structure of the yarn, resulting in quality degradation. For this reason, we propose a spinning cylinder for a coated silk machine that is easy to adjust.

The inner wall of the spring 11 is movably connected with a threaded rod 12. The threaded rod 12 is movably connected with a movable nut 7 at a corresponding position on a side away from the second support frame 4. The movable nut 7 is rotated clockwise to move the threaded rod 12. The movement of the threaded rod 12 will drive the two groups to move toward each other. The toward-each-other movement of the two groups of auxiliary shafts 10 will squeeze the spring 11. When the two groups of auxiliary shafts 10 move, they will be restricted by the limit groove 14 at the bottom of the auxiliary shaft 10, so that the moving position of the two groups of auxiliary shafts 10 is limited.

[0032] Furthermore, a limiting groove 14 is provided at the bottom of the two groups of auxiliary shafts 10, and the inner wall of the limiting groove 14 is movably connected to the limiting column 13, and the other end of the limiting column 13 is fixedly connected to the first support frame 3.

[0036] Working principle:

[0037] When in use, by turning the auxiliary block 20 clockwise, the screw 19 will rotate and move inward to expand the elastic shaft 16. The function of the auxiliary groove 17 is to facilitate the expansion of the elastic shaft 16, and the elastic shaft 16 will support the fixing ring 18 to fix it. Compared with the method of sleeve-connecting the movable shaft at the axis of the spinning drum, this method greatly increases the stability of the spinning drum during operation. When the spinning drum 6 is adjusted, it needs to be placed on the first support frame 3 and the second support frame 4, and the threaded rod 12 is moved by rotating the movable nut 7 clockwise. The movement of the threaded rod 12 will drive the two groups to move towards each other. The two groups of auxiliary The toward-together movement of the auxiliary shafts 10 will squeeze the springs 11. When the two groups of auxiliary shafts 10 move, they will be restricted by the limiting grooves 14 at the bottom of the auxiliary shafts 10, so that the moving positions of the two groups of auxiliary shafts 10 are limited. The limiting columns 13 movably connected to the inner walls of the limiting grooves 14 restrict the movement of the two groups of auxiliary shafts 10. When the two groups of auxiliary shafts 10 move and contact the outer wall of the elastic shaft 16, the rotation of the movable nut 7 is stopped. Otherwise, the rotation is loosened, so that the fixed structures on both sides of the spinning barrel 6 can be clamped and the clamping force can be adjusted. The clamping device adopts elasticity to achieve clamping, which can absorb part of the vibration energy and play a vibration reduction role.
